Madjid al-Farooq was founded in 1976 and is the oldest and largest of the 27 mosques (as of 2008) that have been established in Brooklyn since the 1970s. It is located in a 19,000 square-foot six-story former factory building on Atlantic Avenue constructed in 1928, on a block surrounded by Muslim shops and across the street from the smaller Ahlul Bayt Mosque. The building has belonged to the mosque since 1977.
